Marten identified the linear dynamics of a robotically +balance assisted bicycle showing that the lean rate feedback controller can +stabilize the bicycle at very low speeds and that the time constant of the +instability is significantly reduced when there is a rider onboard. He then +executed an experiment to determine the probability a rider will fall when +perturbed with different magnitude forces at the handlebar. He showed that the +perturbation magnitude and number of prior perturbations were the most +important factors in determining whether one would fall. Lastly, he used these +probabilities to predict a likely reduction in fall probability when the +balance assist system is activated. + +Marten was co-supervised by Leila Alizadehsaravi (TU Delft) and Jason K. Moore +(TU Delft) with assistance from Maarten Pelgrim (Gazelle), Sierd Heida +(Gazelle), Felix Dauer (Bosch), and David Gabriel (Bosch). Everyone at the +bicycle lab is very proud of Marten and wishes him the best in his next +adventures.
